They recently created an advert for a company called Nisshin Seifun Group to celebrate the company’s 110th anniversary.
The advert was storyboarded by Goro Miyazaki, son of Hayao Miyazaki, the character was drawn by producer Toshio Suzuki and the project overseen by Katsuya Kondo. It focuses on a little kitten and is a very sweet little ad. The longest ad (only 30 seconds though) is embedded below.
